Application filed December 16, 1907. Serial No. 406,700.-

To all whom it may concern:

Be it known that I, WILLIAM G. TEMPLE- TON, a citizen of the UnitedStates, residing at Colorado Springs, in the county of El Paso and Stateof Colorado, have invented a new and useful Scale, of which thefollowing is a specification.

The invention relates to weighing scales of that type wherein a'swingingsector or its equivalent is employed and which may be provided withprice or calculating indications or designations, and the object in viewis to simplify the construction of devices of this kind to permit ofmanufacture at a comparatively small cost, while preserving the elementsof accuracy and prompt oise or rest of the parts, means being emp oyedto avoid vibration from one side to the other of the plane of balance orrest.

lVith these and other objects in view, the invention consists in certainnovel features of construction and arrangement of parts, hereinafterfully described, illustrated in the accompanying drawings, andparticularly pointed out in the appended claims, it being understoodthat various changes in the form, proportions, size and minor details ofthe structure may be made without departing from the spirit orsacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a view of a scale embodyingthe construction forming the subject matter ofthe present invention.Fig. 2 is a vertical sectional view of the same. Figs. 3 and 4 are,respectively, transverse and longitudinal sectional views in detail,showing the knife edge and V-support of the load carrier. Fig. 5 is adetail sectional view of the dash pot.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawm s.

n the construction illustrated, the frame or hollow standard 10consisting of a metallic plate or strap arranged to form an invertedstirrup 11 at its upper end, and being open otherwise at its front andsides, is supported by means of braces 12 from a base 13 which may beprovided, as shown, with beveled screws 14. Fixed in registeringopenings 15 in the front and rear sides of the above mentioned invertedstirrup is a knife edge bearing 16 having tongues 17 fitted in saidopenings, and mounted upon said knife edge is a drum 18, having aV-opening 19 to receive the knife edge.

The bearing or sup orting edge of the knife is preferably of a engthcorresponding with the drum, as indicated clearly in Fig. 4, and betweensaid bearing edge and the tongues 17 the knife is cut away as shown at20 to form the tapered ears 21 which are reduced to points at the edgeof the knife for contact with preferably metallic washers or cap plates22, so as to reduce to the minimum any resistance to the vibration oroscillatory movement of the driim by reason of endwise displacementthereof on the knife edge, said washers or cap plates being extendedinward to overhang the V cavity in the drum. Attached to the drum, andpreferably formed as an extension of one of the washers or cap plates,is the sector shaped disk or dial 23, bearing the graduations which, inthe movement of the dial, pass under an indicator wire or rod 24 held bythe frame.

The load carrier consists of a pan 25 supported by a loop 26, which issupported by means of a hook 27 upon a ribbon 28, which encircles aportion of, and is attached at 29, to the drum. The tendency of the loadcarrier to turn the drum is counter-acted by a counter-balance weight30, which is supported by one or more, but preferably two, flexiblecords 31, or the equivalent thereof, which pass over the drum in theopposite direction to the ribbon 28, and are, also, attached thereto. Toneutralize any tendency of the upper end of the hanger 26 to 'swingoutward or forward at its upper end,

a guy runner 32 extends from the uppermost point of the hanger obl'quelyor spirally around the drum, and is attached to the latter.

Beneath the an of the load carrier is arranged an equa izing deviceconsisting of a frame 33 pivotally connected with the load carrier atits outer end, and with the'frame or standard braces 12 at its rear end.

To eliminate the vibration of the'load carrier, a dash pot 34, as shownin detail in Fig. 5 is employed, the same consisting of a receptacle 35for oil or similar liquid, in which operates a plunger 36 carried by aca 37 w 1ich is connected to an arm 38 on the oad carrier, said plungerpreferably being of cone shape open at its lower and larger end, andprovided at its apex with a reduced vent 39, to permit the gradualescape or entrance of air during the Vertical movements of the plunger.The receptacle 35 may, as illustrated, be exteriorly threaded, and theupper reduced portion of the cap may be simi arly interiorly threaded toengage the same when the scale is not in use, or is being shifted.

I claim 1. In a scale, the combination with a supporting frame, of aknife edge bearing supported thereby, a drum having av engaging saidknil'e edge, a load receiver flexibly connected with the drum, andcounter-balancing devices for the load receiver also connected with thedrum.

2. In a scale, the combination with a supporting frame, of a knife edgebearing, a drum having a terminally closed V engaging said knil'e edge,the extremities of the knife edge being reduced for contact with theboundary walls of the V, a load receiver, and countcrbalancing devicesconnected with the drum.

In a scale, the combination with a supporting frame, of a knife edgebearing, a drum having a V engaging the knife edge bearing, terminalwashers or cap plates closbeing terminally reduced for contact with thewashers or cap plates, a load receiver,-

and counter-balancing devices connected with the drum.

4. In a scale, the combination with a supporting frame, of a knife edgehaving terminal tongues engaging openings in the frame, and having itsbearing edge reduced terminally to points, a drum having a V en gagingthe knife edge, said V being terminally closed, a load receiver, andcounter-balancing devices connected with the drum.

5. In a scale, the combination with a supporting frame, a drum, and aload receiver having llexible connection with the drum, ol a guyconnected with the load receiver below the plane of the drum andobliquely or spirally coiled upon said drum.

In testimony that I claim the foregoing as my own, I have hereto aliixedmy signature in the presence of two witnesses.
